DETAILED DESCRIPTION OF THE DRAWINGS

The present disclosure is further described in combination with the following embodiments and the accompanying drawings so as to help the skilled in the art to better understand and practice the disclosure. However, the embodiments set forth herein should not be regarded as limitation of the present disclosure.

FIGS. 2-1, 2-2, 2-3 and 2-4 show a RBG synchronous intelligent light string assembly comprising an intelligent power supply, a plurality of light strings and a main wire, wherein the plurality of light strings are connected in parallel to the main wire.

In an embodiment of the disclosure, a plurality of light strings 1 are connected in parallel to a main wire 2. The plurality of light strings 1 extend downward and vertically and are evenly spaced along the main wire 2. Each light string 1 comprises of a plurality of RGB diodes 3 connected in series. The longest light string is located in the middle of the wire 2 and the light strings of both sides are shorter in length in sequence as being away from the longest light string. A male joint 4 is arranged on one end of the main wire 2 and a female joint 5 is arranged on the other end of the main wire 2. A PE heat shrinkable sleeve 6 is arranged outside each of the male joint 4 and female joint 5.

In another embodiment of the disclosure, the plurality of light strings 1 are connected in series to form an elegant curtain-like appearance.

As shown in FIGS. 2 and 3, a first end of a plug 7 is electrically connected to a 220 V power supply and a second end of the plug 7 is connected to a control unit. The control unit comprises, in sequence, a fuse for current limitation, a varistor for voltage control, a filter for filtering out noise and separating signals, a filter circuit for passing the low frequencies and attenuating the high frequencies; outputs of the filter circuit are respectively connected to an input of the MOSFET and a DCDC transformer. The DCDC transformer outputs a direct current with an altered voltage to a driver and an IRF. The IRF is connected with a program module, a remote-control module, a WiFi & Bluetooth module, these modules are all configured with switches. A signal from the IRF goes through a heat dissipation component and the driving module. Both of outputs of the driving module and the DCDC transformer are connected to an input of MOSFET while an output of MOSFET is connected to one end of the main wire.

According to an embodiment, the fuse functions as below: when the circuit malfunctions or creates anomalies, the current keeps rising and it probably destroys some crucial devices or expensive devices in the circuit. Consequently, the circuit probably burns out or even a fire can be caused. If a fuse is properly arranged, it will melt when the current abnormally increases to a certain level within a certain time, and thereby interrupting the current and allowing safe operation of the circuit.

The fuse is connected to the varistor via a circuit board and the varistor is a protective device for voltage limitation. With the non-liner characteristic of the varistor, it can clamp the voltage to a certain value when overvoltage is applied thereon in order to protect the subsequent circuit.

The varistor is connected to the filter via the circuit board. The filter is a circuit or an operating and processing system that is capable of frequency selection, and plays a role in filtering noise and separating a variety of signals.

According to an embodiment of the present disclosure, the filter is a circuit or an operating and processing system that is capable of frequency selection and plays a role in filtering noise and separating a variety of signals. Via the circuit board, the filter is connected to the filter circuit which is configured for allowing passing a current with a certain frequency or attenuating a current with a certain frequency. There are four basic filtering circuits: high-pass filter (high frequencies are passed, low frequencies are attenuated), low-pass filter (low frequencies are passed, high frequencies are attenuated), band-pass filter (only frequencies in a frequency band are passed) and band-stop (trap) filter (only frequencies in a frequency band are attenuated).

According to an embodiment of the present disclosure, the filter circuit is connected to the DCDC transformer via the circuit board. Specifically, the input direct current is converted to an alternating current through a self-oscillating circuit, and further converted to a direct current at an altered voltage transformed by the transformer for output, or further converted to a high-voltage direct current by a voltage doubling rectifier circuit for output.

The DCDC transformer converts the input direct current to an alternating current through a self-oscillating circuit, and further converted to a direct current at an altered voltage transformed by the transformer for output, or further converted to a high-voltage direct current by a voltage doubling rectifier circuit for output.

According to an embodiment of the present disclosure, the DCDC transformer is connected to the IRF via the circuit board. There are two main types of field-effect transistors. For metal-oxide semiconductor FET, MOS-FET for short, majority carriers participate in conducting, so it is also named as unipolar transistor, which belongs to a voltage-controlled semiconductor device and has advantages such as high input resistance (1-10Ω), low noise and low power-consumption, wide dynamic range, great facility for integration, wide safe operating region without second breakdown.

The DCDC transformer is connected to a WiFi & Bluetooth module, a remote-control module and a program module via the circuit board. The WiFi & Bluetooth module is a PCBA integrating functions of WiFi and Bluetooth for short-range wireless communication, and it is composed of a data module and a vocal module. The WiFi & Bluetooth module is mainly used in the field of short-range data transmission and it is handy to be connected with a Bluetooth or WiFi device of a PC, a phone and a tablet computer to avoid tedious cable connecting and to take the place of serial link. The remote-control module is configured for controlling and function switching transmission while the program module refers to the component for editing or correcting the functional program file of the product.

Outputs of the WiFi & Bluetooth module, the remote-controlling module and the program module are connected to the IRF via the circuit board.

Output of the IRF is connected to the heat dissipation component configured as a temperature protection assembly.

Outputs of the DCDC transformer and the heat dissipation component are connected to an input of the driver which is configured for simulating the upper level module of the module to be test and is equivalent to the main program of the module to be test. An output of the driving module is connected to the MOSFET via the circuit board and an output of the MOSFET is connected to the load, wherein the MOSFET is a field-effect diode widely used in analog and digital circuits.

As shown in FIG. 3, the DCDC transformer converts an alternating current to a direct current.

As also shown in FIG. 3, the WiFi & Bluetooth module is controlled via a wireless terminal.

According to an embodiment of the present disclosure, one of the switches of program module, remote-control module and the WiFi & Bluetooth module is turned off, and a closed circuit is formed.
